What is the definition of an additive in the context of septic systems?

In the context of septic systems, an additive is defined as a commercial product that is specifically designed to enhance the performance of the system. These products may help in breaking down solids, improving the efficiency of the bacterial action within the tank, and assisting in the treatment of effluent before it is dispersed into the drain field. The additives can increase the overall functionality and lifespan of the septic system by addressing specific issues like excessive buildup or slow drainage.

While aesthetic purposes might be a consideration for some products, they do not serve the primary function required in managing waste. A chemical that stabilizes sewage might suggest a function similar to that of an additive, but it does not encompass the broader spectrum of performance improvement that additives are designed for. Recommendations from a local health officer can provide important guidance, but they do not define an additive's role or function within a septic system.
